AT&T's regular and Premier sites broke down and folded for much of the initial 2 hours of the pre-order period. I got mine in at Apple for delivery next Friday, 9/21, but now, it's already showing 2 weeks on all 3 carriers as the delivery ETA. Dang, that was quick!
The good thing about the Apple site is that it will show your unlimited plan if you have it and whatever other features you have with "NO changes", so I took a bunch of screen shots to make sure to quash any inconsistencies, should they arise! :-D
